Issues with Synchronize to and from DB (version 3.3.0.747)

Question

Having an issue with syncing the model and the data dictionary is a very specific case:
1. Reverse engineer an existing table (T1)
2. Copy the table (in data modeler) - T2
3. Rename the table, make changes (add columns and keys)
4. Forward engineer the new table (i.e., export and run DD for T2L)
5. Make additional changes to new table (T2) in data model.
6. Run sync db with model - the sync routine compares my new table (t2) to the original table (T1) in the database! It cannot "find" my new table (T2) in the database to compare to.
7. Alternatively try to sync the model with the db - this time it wants to sync the original table (T1) to itself (which has no change) and DROP my new table (T2) from the model.
It appears that sync is looking at meta data one my new table (T2) that contains the original copied table's name (T1). And in fact if I look at the table Summary properties - the source db object property does list the original table name (T1).
I also tried to reverse engineer the new table (T2) to the merge with the model, that has the same behavior as the sync.
Is there a way to fix this short of dropping T1 from the schema?

Hi Kent,
thanks for reporting the problem. I logged a bug and ER for that.
Is there a way to fix this short of dropping T1 from the schema?Unnecessary information about source need to be cleared. Here is a script that will help on that:
//array with 2 elements to illustrate different use cases - the first is used to have exact match on table name
// the second one ("REGIO") can be used with following check in inList function
//if(table.getName().startsWith(list)){
var list = ["Regionsv1","REGIO"];
function isInList(table){
     for(var i=0;i<list.length;i++){
          // different approaches to match table name can be used
          // be aware of letter case
          //if(table.getName().startsWith(list[i])){
          if(table.getName().equalsIgnoreCase(list[i])){
               return true;
     return false;
function clearSourceStampforTable(table){
     clearSourceStamp(table);
     cols = table.getElements();
     for(var i=0;i<cols.length;i++){
          clearSourceStamp(cols[i]);
     keys = table.getKeySet().toArray();
     for(var i=0;i<keys.length;i++){
          clearSourceStamp(keys[i]);
          if(keys[i].isFK()){
               clearSourceStamp(keys[i].getFKIndexAssociation());
function clearSourceStamp(object){
     object.setSourceConnName("");
     object.setSourceObjSchema("");
     object.setSourceObjName("");
     object.setSourceDDLFile("");
     object.setDirty(true);
tables = model.getTableSet().toArray();
for(var i=0;i<tables.length;i++){
     table = tables[i];
     if(isInList(table)){
          clearSourceStampforTable(table);
